A summer outage is an inconvenience. A winter outage is a safety event: no heat, food spoiling, pipes at risk, and roads too icy for a supply run. Winter storms also last longer — multi-day outages are the norm, not the exception — which changes what to buy. You need capacity for days, not hours; a battery chemistry that survives the cold; and a plan for the one thing most buyers get wrong about winter batteries. Here are the five stations that actually hold up, and the cold-weather rules that keep them working.
What actually matters when the outage lasts 3 days
- Capacity beats output. A 2,400W station with 1 kWh dies in hours; a 1,800W station with 3.8 kWh keeps the fridge alive for days. Size for total energy first, peak watts second.
- Heat is a separate problem. Portable stations cannot run space heaters (1,500W each — they'd drain a 2 kWh station in about an hour). Winter warmth comes from indoor-safe propane heaters, 12V heated blankets, and battery heated vests — all far cheaper in watts than heating a room. The station's job is the fridge, the phones, the lights, and recharging those small batteries.
- Solar barely helps in a winter storm. Short days, low sun angles, snow-covered panels, and heavy cloud can cut output to 10–20% of rated watts. Treat solar as a day-three bonus, not the plan — size the battery for the worst day.
- Red Cross basics still apply: a gallon of water per person per day, three days of non-perishable food, flashlights, a battery or hand-crank radio, medications, blankets, and cold-weather clothing. The station is one item in the kit, not the kit.
Our picks
| Pick | Capacity | AC output | Discharge temp | Charge temp | Weight | Price range |
|---|---|---|---|---|---|---|
| Anker SOLIX F3800 Best whole-home winter pick | 3,840Wh | 6,000W | −20°C to 40°C | 0°C to 40°C | 132 lbs | $1,700–$2,200 |
| EcoFlow DELTA 2 Max Best multi-day mid-size pick | 2,048Wh | 2,400W | −10°C to 45°C | 0°C to 45°C | 50 lbs | $1,000–$1,300 |
| Jackery HomePower 2000 Plus v2 Best current Jackery pick | 2,048Wh | 2,400W | −10°C to 45°C | Check manual* | Check listing* | $1,000–$1,200 |
| BLUETTI AC180 Best cold-weather value pick | 1,152Wh | 1,800W | −20°C to 40°C | 0°C to 40°C | ~35–36 lbs | $425–$500 |
| EcoFlow DELTA 2 Best budget winter pick | 1,024Wh | 1,800W | −10°C to 45°C | 0°C to 45°C | 27 lbs | $600–$1,000 |
Specs verified November 2026 from manufacturer manuals and spec pages. *Jackery's v2 weight and charging-temperature figures conflicted across sources at research time (and one source lists sub-zero charging, contradicting standard LiFePO4 guidance) — verify both on the US product page/manual before relying on them. The DELTA 2's current standalone US price and stock vary as the model transitions; the range above reflects recent MSRP and sale figures. Prices swing with sales — ranges, not live prices.
Fridge runtime: the number that decides the pick
A modern full-size fridge draws roughly 100–200W while the compressor runs, with a much higher startup surge. Using Wh × 0.85 ÷ watts, here are continuous-draw estimates — conservative, because a cycling fridge draws far less around the clock than its running wattage:
| Station | Usable energy (est.) | At continuous 150W | At continuous 100W |
|---|---|---|---|
| Anker SOLIX F3800 | ~3,264Wh | ~21.8 hrs | ~32.6 hrs |
| EcoFlow DELTA 2 Max | ~1,741Wh | ~11.6 hrs | ~17.4 hrs |
| Jackery HomePower 2000 Plus v2 | ~1,741Wh | ~11.6 hrs | ~17.4 hrs |
| BLUETTI AC180 | ~979Wh | ~6.5 hrs | ~9.8 hrs |
| EcoFlow DELTA 2 | ~870Wh | ~5.8 hrs | ~8.7 hrs |
Estimates only. A cycling fridge typically lasts longer than these continuous-draw figures suggest — and deep cold reduces usable capacity, so treat these as fair-weather numbers, not guarantees.
Anker SOLIX F3800
For a winter storm, the F3800 is the only pick here that can plausibly carry a house: 3,840Wh, 6,000W of 120V/240V split-phase output, expandable to 26,880Wh with six batteries — and a discharge rating down to −20°C, so it keeps working in a freezing garage. The 132-lb wheeled unit belongs parked, not carried, and at $1,700–$2,200 on sale (against a $3,999 list) it's a serious purchase — but it's the one station here where "multi-day outage" doesn't require rationing the fridge. Don't confuse it with the newer F3800 Plus, which has different solar specs and pricing.
Pros
- 3,840Wh expandable to 26.9 kWh — true multi-day capacity
- 6,000W split-phase output; discharges to −20°C
- 240V outlets for transfer-switch setups
Cons
- 132 lbs — wheeled, not portable
- List price is steep; buy on sale only

EcoFlow DELTA 2 Max
The DELTA 2 Max is the sensible middle of this roundup: 2,048Wh and 2,400W out of the box, expanding to 6,144Wh with two extra batteries, LiFePO4 rated 3,000 cycles to 80%, and 1,000W of solar input for the days when the sun does come back. At 50 lbs it's a garage-to-kitchen carry, not a one-hand lift. For most households, the base unit covers a day of essentials and one expansion battery covers the second day — that's the whole winter plan in one purchase path.
Pros
- 6,144Wh expansion ceiling for multi-day outages
- Dual solar inputs for post-storm recharging
- 2,400W output with 3,400W X-Boost
Cons
- Discharge floor is −10°C, not −20°C like the Anker/BLUETTI picks
- Expansion batteries add ~$899 each

Jackery HomePower 2000 Plus v2
A naming warning first: Jackery now sells two different products under near-identical names. The original Explorer 2000 Plus (2,043Wh, 3,000W, ~61.5 lbs) is now mostly kits and refurbished stock. Its successor, the HomePower 2000 Plus v2 (US name; Explorer 2000 Plus v2 in the UK/EU), is the current model: 2,048Wh, 2,400W output, LiFePO4 rated 6,000 cycles to 70%, expandable to 12 kWh. Buy the v2, not leftover original stock — and don't let a listing mix their specs. Two figures to verify on the US page before purchase: the v2's weight (sources conflict) and its charging-temperature floor (one source lists sub-zero charging, which contradicts standard LiFePO4 guidance and may reflect an unconfirmed self-heating design).
Pros
- Current model, in stock — unlike the original
- 2,048Wh expandable to 12 kWh
- 6,000-cycle LiFePO4 rating (to 70%)
Cons
- Original-vs-v2 naming confusion is real — check the model
- Weight and charging-temperature figures need US-page verification

BLUETTI AC180
The AC180 is the only sub-$500 pick here rated to discharge down to −20°C — a genuine winter differentiator — with 1,152Wh of LiFePO4 rated 3,500+ cycles to 80% and 1,800W output. It's a one-day fridge pick, not a multi-day one (see the runtime table), but at $425–$500 it's the cheapest way to keep food safe through the first night of a storm, and it pairs naturally with the low-watt warmth gear below. Note the manual-revision weight variance (~35–36 lbs) and that charging still stops below 0°C, like every LiFePO4 unit here.
Pros
- Discharges to −20°C — best cold rating at this price
- 3,500+ cycle LiFePO4; 1,152Wh for ~$425–$500
- UPS mode (≤20 ms) for the home office
Cons
- Not expandable — one day of fridge, not three
- Charging still stops below freezing

EcoFlow DELTA 2
The DELTA 2 is the entry point to this roundup: 1,024Wh, 1,800W, LiFePO4 rated 3,000+ cycles to 80%, at 27 lbs. It's a phones-lights-fridge-top-up pick, not a multi-day fridge pick — but it expands to 2,048Wh or 3,040Wh with extra batteries, which is the upgrade path if the first storm teaches you that 1 kWh wasn't enough. Caveat: the model is transitioning as the DELTA 3 line arrives, and standalone US stock varied at research time — check availability, and treat the $600–$1,000 range as MSRP-to-sale, not a live price.
Pros
- Lightest full-size pick here (27 lbs)
- Expandable to 2,048Wh or 3,040Wh
- 3,000+ cycle LiFePO4
Cons
- 1,024Wh is a one-night fridge pick, not multi-day
- Stock varies as the model transitions

The cold-weather rule that breaks winter batteries
The 3-day winter outage plan
- Day one: fridge on the station, phones and lights on the station, warmth from propane heat and heated blankets/vests — not from the station. Keep the station indoors.
- Day two: if you have expansion batteries, this is when they earn their money. If not, ration: fridge in the coldest part of the cycle, phones on a power bank, lights only at night.
- Day three: recharge window. If the sun returns, deploy panels (snow-cleared, angled steep for low winter sun). If the grid returns in bursts, charge the station first — it's your bridge to the next outage.
